First, based on Fig. 1, Fig. 2, the overview of the rotation driving mechanism of an embodiment of the invention is described.

Rotation driving mechanism is configured to comprise: the driver part 101 arranged regularly and opposed with this driver part 101 and link with the axis of rotation 112 driven member 103 arranged, and is configured to the axis of rotation 112 rotation along with the movement of driven member 103.

And, as shown in Figure 1, driven member 103 has tapered portion 104 and cylindrical part 106, using by as the N pole of follower, S pole form multiple by driving magnetic pole 105, circumference along tapered portion 104 and cylindrical part 106 is set to equal angles spacing, and arranges in the mode making spacing reduce continuously from side direction path side, large footpath.

As shown in Figure 2 a, the multiple driving magnetic poles 102 be made up of N pole, S pole as driving mechanism of driver part 101, with with above-mentioned driven member 103 by the mode driving the axial arbitrary position of the rotation of magnetic pole 105 opposed, be arranged at the rake 115 of support 114 and par 116.

And, the spacing of the driving magnetic pole 102 of driver part 101 is set to: with driven member 103 driven magnetic pole 105 from mode corresponding to the reduction of the spacing of side direction path side, large footpath, make spacing be driven the movement direction of magnetic pole 105 to change along above-mentioned, and the spacing of above-mentioned driving magnetic pole 102 is set to with driven the opposed arbitrary position of magnetic pole 105 to become uniform distances accordingly.

In addition, the driving magnetic pole 102 of above-mentioned driver part 101 towards, be relative to driven member 103 by drive magnetic pole 105 produce attraction force towards, in addition as shown in Fig. 2 b ~ Fig. 2 e, above-mentioned driving magnetic pole 102 is driven magnetic pole 105 close in a non-contact manner with driven member 103, namely with the mode with gap opposed configure.

The action of the rotation driving mechanism formed like this is described.

Such as, if linked the driven member 103 of the axis of rotation 112, move from illustrated left direction right direction relative to the driver part 101 shown in Fig. 2 a, the driven member 103 then linked with the axis of rotation 112 driven magnetic pole 105, drive because of the attraction force of the driving magnetic pole 102 of driver part 101, thus the axis of rotation 112 rotates.

Now, as mentioned above, the spacing of the rake 115 of driver part 101 and the driving magnetic pole 102 of par 116 is set to: become uniform distances accordingly with the tapered portion 104 of driven member 103 and the opposed arbitrary position of magnetic pole 105 that driven of cylindrical part 106, therefore driven member 103 is driven in rotation and does not slide.

And, the driving magnetic pole 102 of driver part 101 is driven the opposed position of magnetic pole 105 to be set to driven member 103: along driven the axis of rotation of magnetic pole 105 (driven member 103) to and movement direction change continuously, therefore, it is possible to make that the rotational speed of driven member 103 is stepless to be changed smoothly.

In addition, in the present embodiment, although drive magnetic pole 102 with driven magnetic pole 105 with the spaced mode of tool opposed configure, also can make both arranged opposite contiguously.

In addition, although be provided with cylindrical part 106 in driven member 103, driver part 101 is provided with par 116, this cylindrical part 106, par 116 also can be omitted.

In addition, also bevel gear can be set in the tapered portion 104 of driven member 103, and to make the engaging parts such as according to the position opposed with this bevel gear pin that spacing the changes mode outstanding to driver part 101 arrange, thus by this engaging, rotary actuation is carried out to driven member 103.

Correspondence is described with the film label sticking device of an embodiment of the invention of above-mentioned rotation driving mechanism.

As in Fig. 3, outline represents, film label sticking device 100 possesses: be provided with the main turntable 110 of multiple moving body 111, supply the tank body supply roll 150 of tank body CA to the moving body 111 of main turntable 110, discharge the tank body of tank body CA discharge wheel 160 and opposed with main turntable 110 and film label is pasted on the film label Sticking roller 170 on the surface of tank body CA from the moving body 111 of main turntable 110.

The tank body CA supplied from tank body supply roll 150 remains on the axle 113 (referring to aftermentioned) being arranged at moving body 111, revolved round the sun by main turntable 110 and while move continuously on revolution orbit, suitably rotation on one side, at label sticking area LP sticking film label, and in order to paste securely, tank body CA is expelled to tank body and discharge wheel 160 after area pressed PP press film label from the side again.

Keeping the moving body 111 of tank body CA, be provided with the driven member 103 for making tank body CA rotation, before area pressed PP again, be set with the acceleration region KP that the speed of autorotation of tank body CA is accelerated, and be set with the decelerating area GP that the speed of autorotation of tank body CA is slowed down after area pressed PP again.

In the present embodiment, at acceleration region KP, again area pressed PP and decelerating area GP, the mode opposed with driven member 103 is provided with driver part 101, this driver part 101 makes tank body CA change along with the speed of autorotation of movement.

Near label sticking area LP, moving body 111 is configured to move on the track along film label Sticking roller 170 (referring to aftermentioned), before label sticking area LP, separate suitable displacement distance and be provided with the heating region heating tank body CA.

In addition, tank body supply roll 150 and tank body discharge the heating process of tank body CA in the handing-over of the tank body CA between wheel 160 and main turntable 110 and heating region, utilize known mechanism to carry out.

The concrete structure of main turntable 110, is shown in Fig. 4 and Fig. 5 of the direction view as Fig. 3 A and Fig. 3 C.

The rotatable earth's axis of main shaft 122 of main turntable 110 is supported on the framework 121 separating predetermined distance and arrange, and solid of rotation 123 is fixed on this main shaft 122 and rotates integratedly with main shaft 122.

Can the support plate 124 of displacement in the radial direction, the peripheral part of solid of rotation 123 is supported on via a pair rest pin 125, moving body 111 is fixed on this support plate 124, has the axis of rotation 112 of the axle 113 keeping tank body CA, can be supported on this moving body 111 rotatably.

Rest pin 125 can be embedded in embedding hole 126 slidably, this embedding hole 126 is arranged at solid of rotation 123 equidistantly radially to run through, the two ends of the length direction of support plate 124 are provided with cam follower 127, and this cam follower 127 is entrenched in the cam path 128 of the framework 121 being formed at both sides.

If solid of rotation 123 rotates along with the rotation of main shaft 122, the support plate 124 being then arranged at its periphery equally spacedly rotates, support plate 124 is fettered by cam path 128, thus with the shape displacement on the radial direction of solid of rotation 123 accordingly of cam path 128, while rotate.

In the present embodiment, cam path 128 is ring-type, and except near above-mentioned label sticking area LP, be formed as circular, and the moving body 111 being fixed on support plate 124 moves on revolution orbit.

Near label sticking area LP, cam path 128 is formed to cave in the radial direction along the mode of film label Sticking roller 170, and increases the tracking angle of itself and film label Sticking roller 170.

Thereby, it is possible to make label sticking area LP be formed longer, can paste reliably in high-speed production lines.

In addition, utilize the double-cam structure being provided with cam path 128 in both sides, to support plate 124, support, therefore constructing phase specific rigidity with cantilever support increases, and can obtain higher application pressing force, and it is stable that film label is bonded, thus realizes speed up.

Be rotatably freely supported on the axis of rotation 112 of moving body 111, and in the end of the side contrary with keeping the axle 113 of tank body CA, be fixed with driven member 103.

The support 114 of driver part 101 is fixed on the outer circumferential face of framework 121, the tapered portion 104 of driven member 103 opposed with the driving magnetic pole 102 of the rake 115 of driver part 101 by driving magnetic pole 105, thus forms above-mentioned rotation driving mechanism.

In the region being provided with driver part 101, if moving body 111 moves, then driven member 103 rotary actuation with this moves because of the rotation of main shaft 122, thus be held in axle 113 tank body CA rotation, while mobile.

As shown in Figure 5, in area pressed PP again, abut for above-mentioned tank body CA and the pressing pad 129 rotated along with the movement of tank body CA, be arranged on the side identical with driver part 101 relative to the axis of rotation 112.

In area pressed PP again, pressing pad 129 is directly connected to the side of tank body CA, is rotated and carry out rotation driving by tank body CA, and therefore its speed of autorotation depends on that the diameter of tank body CA specifies.

Usually, depend on the speed of autorotation of the diameter of this tank body CA, for the high speed that the speed of autorotation of the tank body CA of the best of the operation than other positions is high, if tank body CA is connected to pressing pad 129 with lower speed of autorotation, then power puts on the circumference of the tank cylinder of tank body CA, thus there is the problem causing pasted film label surface damage, film label generation fold and so on because of friction.

In addition, when the best speed of autorotation of the operation after area pressed PP is again low speed, to need longer region if exist before speed of autorotation becomes low speed or slow down rapidly after the above-mentioned PP of area pressed again, then can apply the problem of load and so on to clutch etc.

Therefore, in the present embodiment, by arranging acceleration region KP before area pressed PP again, decelerating area GP is set after area pressed PP again and at acceleration region KP, again area pressed PP and decelerating area GP, driver part 101 is set in the mode opposed with driven member 103 and is formed above-mentioned rotation driving mechanism, thus can in shorter region, utilize rotation driving mechanism that tank body CA is changed energetically along with the speed of autorotation of movement, solve the problem thus.

As shown in Figure 3, acceleration region KP after label sticking area LP, from the position that the mobile route of moving body 111 returns revolution orbit.

As shown in Figure 6, in the initial position of this acceleration region KP, the driving magnetic pole 102 of the rake 115 of driver part 101, opposed by the position of the largest diameter driving magnetic pole 105 with the tapered portion 104 of driven member 103.

And, the driving magnetic pole 102 being configured to this driver part 101 and driven member 103 by the position driving magnetic pole 105 opposed, along with the movement of tank body CA slowly to the position transfer that diameter is little, and through the neutral position shown in Fig. 7, in the end position of acceleration region KP that is the initial position of area pressed PP again, as shown in Figure 8, the driving magnetic pole 102 of the rake 115 of driver part 101 is opposed with the position equal with tank body CA by the diameter of driving magnetic pole 105 of the tapered portion 104 in driven member 103.

So, during making acceleration region KP movement, the speed of autorotation of tank body CA be accelerated for directly and pressing pad 129 to abut the speed of autorotation obtained equal, the speed of autorotation that tank body CA starts when abutting with pressing pad 129 can be eliminated poor, thus pasted film label surface damage can not be caused because of friction, film label can not be made to produce fold.

In addition, in decelerating area GP the end position from area pressed PP again, contrary to the above, be configured to: what opposed locations made the driving magnetic pole 102 of the rake 115 of driver part 101 gently to the tapered portion 104 of driven member 103 along with moving of tank body CA is driven the position transfer that the diameter of magnetic pole 105 is large, thus the speed of autorotation of tank body CA is slowed down, the process of operation is afterwards carried out immediately after shorter decelerating area GP.

In addition, in the present embodiment, although only arrange driver part 101 at acceleration region KP, again area pressed PP and decelerating area GP, but when other regions also need rotation on one's own initiative to drive to change speed of autorotation, also can for above-mentioned each region discontinuously or comprise above-mentioned zone driver part 101 is set continuously interior.

In addition, in the present embodiment, although driven member 103 adopts the structure only with tapered portion 104, but the situation longer in the region driven with certain speed of autorotation is inferior, also can adopt the driven member 103 being provided with the cylindrical part with the radius corresponding with this speed of autorotation, make by cylindrical part transmission of drive force more reliably.

Further, driven member 103 links via overrunning clutch and the axis of rotation 112, thus also can realize limit by above-mentioned rotation driving mechanism carry out drive limit carry out rotation driving by other mechanisms with the speed faster than tank body CA.

So the driving force produced by other mechanisms such as only becomes and the driving force needed for the acceleration of the residual quantity of the speed of autorotation produced by rotation driving mechanism, thus can reduce brought to tank body CA, other mechanisms above-mentioned by this driving force infringement, load.
